When system enter suspend, we can set the DDR IO
to high-Z state to save DDR IO's power, this operation
can save many power(from ~26mA@1.5V to ~15mA@1.5V,
measured on i.MX6Q/DL SabreSD board, R25) of DDR IO. To
achieve that, we need to copy the suspend code to ocram
and run the low level hardware

So, imx6_suspend() takes no arguments.

Oh, it takes one argument.
